SPECIFICATION forming part of Letters Patent No. 565,849, dated August11, 1896.

Application filed February 5, 1896. Serial No. 578,120. (No model.) I

To all whom it mag concern:

Be it known that I, ALEXANDER ERKLIN, of New York city, in the countyand State of New York, have invented a new and useful Improvement inWindow-Frames, of which the following is a full, clear, and exactdescription.

My invention relates to an improvement in window-frames, or frames forsashes, and the object of the invention is to provide frictionrollers inthe sash-grooves of the frame, the said rollers being provided with ayielding or spring support, whereby they will constantly bear upon thewindow-sashes while the said sashes are within the frame, no matterwhether the sashes be in a lower or in an upper position.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming apart ofthis specification,

in which similar characters of reference inclicate corresponding partsin all the figures.

Figure 1 is a front elevation of a windowframe containing sashes, theframe having the improvements applied thereto, and a por tion of theframe being in section to disclose one set of friction-rollers. Fig. 2is a vertical section through the window frame, taken practically ontheline 2 2 of Fig. 1. Fig. 3 is a section through a portion of thewindowframe, the said section being taken at right angles to the sectionshown in Fig. 2, and substantially on the line 3 3 of the latter figure.Fig. 4 is a detail view of a portion of the upper or fixed section ofthe window-sash stop.

Fig. 5 is a perspective view of the removable for engagement with theinclined surface of the abutting section; and the removable section ofthe parting-strip B is fitted in a suitable groove 13, made in theframe, as shown best in Fig. 2.

The division in the parting-strip B is so made that when the upper andlower sashes G and D are in their closed position the connection betweenthe two sections of the parting-strip willbe at or near a point abovethe upper edges of the meeting-rails of the said sashes. One of theinner-sash stops E is preferably made in two sections, an upper section14 and a lower section 15. The upper section 14 may be secured to theframe in the usual manner, and where the two sections of the outer-sashstop connect their opposing faces 16 are correspondingly beveled, andalso the connection between the two sections of the sash-stop is madepreferably at or near a point horizontally opposite to the connectionbetween the sections of the parting-strip B- The lower removable section15 of the innersash stop is provided with a groove 17 in its 'upperedge, as illustrated in Fig. 5, the said groove being adapted to receivea web 18, preferably of metal, which is ordinarily in the centralportion of the lower face of the upper or fixed section 14, and inaddition to the locking engagement thus made between the opposing endsof the two sections of the sash-stop the lower removable section of thesash-stop E is usually provided at or near its lower end with a bolt 19,or its equivalent, adapted to enter a suitable keeper in the sill of thewindow-frame.

In order that the sashes may be raised and lowered with the leastpossible amount of resistance, and, furthermore, inorder to prevent thesashes from having a rattling move ment in the window-frame, I providefor each window-sash at each of its sides a tension device F. Eachtension device comprises a face-plate 20, having openings 21 at eachside of its center, through which extend portions of the peripheries offriction-rollers 22. These friction-rollers are ordinarily pivoted inhorizontal brackets or hangers 23, and the hangers are secured to theend portions of a spring 24, the said spring being secured at or nearits center, preferably upon the inner end of a post 25, projected fromthe inner surface of the face-plate 20 about midway between thefriction-rollers 22. Two of these tension devices are located at eachside of the window-frame, one being placed in each of the sashgrooves,and the location of the tension devices is such that when the lower sashis in its closed position one of the rollers of each tension devicebelonging to that sash will be above the upper face of the upper rail ofthe sash, the lower rollers engaging with the side edges of the sash,and when the upper sash is in its upper position one roller of itstension device will be in engagement with the sash and the other belowit, so that no matter how the two sashes are moved in the window-framethey will be in engagement With the two friction-rollers, one at eachside. The tension devices are located in suitable recesses 26, made inthe sashgrooves, the outer portions of the said recesses being closed bythe face-plate 20 of the said tension devices.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination, with a window-frame,

of tension devices adapted for engagement with the sashes, the saiddevices being located in recesses produced in the back wall of thesash-grooves of the frame, each device comprising an aperturedface-plate, having a central support on its rear face, a spring securedto said support at the center of its length, and friction-rollersattached to the end portions of the spring, a portion of theirperipheral surfaces extending through an opening in the face-plate, asand for the purpose specified.

2. A tension device for windows, consisting of a face-plate having anopening near each end and provided with a post projecting from its rearface, a spring secured at the center of its length to the post, bracketson the ends of the spring, and rollers mounted in the brackets andprojecting into the openings of the face-plate, substantially as hereinshown and described.
